A rising craft beer brand in Zhejiang Province has quickly gained popularity among young consumers thanks to its unique fruit-flavored brewing process. To cope with the surge in orders during the summer peak season, the brand decided to upgrade its production capacity from traditional workshop-style production to modern, large-scale operations. However, during the production line upgrade, the company faced three core pain points: First, craft beer is extremely sensitive to oxygen, and traditional filling methods easily lead to excessive oxygenation, damaging the original fresh flavor of the beer; second, craft beer packaging iterates rapidly, requiring frequent switching between PET bottles, glass bottles, and even cans, making changeover time extremely long with traditional production lines; third, the high cost of new factory rentals necessitates a highly integrated, compact filling machine that balances high quality and cost-effectiveness.

Following its successful commissioning and delivery, the PET craft beer 5-in-1 bottling production line has demonstrated excellent performance across various metrics. Customer feedback includes: **Double Reduction in Space and Cost:** The compact 5-in-1 design saves the customer approximately 40% of factory floor space, significantly reducing initial infrastructure costs and subsequent factory rental expenses.

**Double Enhancement in Flavor and Quality:** Micro-oxygen bottling technology significantly improves the shelf life and taste stability of craft beer. After its market launch, the product’s authentic flavor has resulted in a very high repurchase rate.

**Double Increase in Changeover Efficiency:** The flexible design reduces the changeover time between different packaging sizes to less than 30 minutes, allowing the company to easily handle the rapid launch of various limited-edition holiday products and collaborations.

**Stable and Reliable Operation:** The equipment operates with an extremely low failure rate under 24-hour continuous operation. Its high degree of automation requires only two operators per line for daily inspections and material replenishment, significantly reducing labor costs.
